DOUGH-RAISING DEVICE Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed February 21,1907. Serial No. 358,617.

To all whom it may concern:

Be it known that I, MINTA M. GILL, a citizen of the United States of America, residing at Turtle Creek, in the county of YAllegheny and State of Pennsylvania, have invented certain new and useful Improvements in Dough-Raising Devices, of which the following is a' lto be raised.

In connection with the device, I employ novel means for heating the same and regulating the ventilation of the device, whereby any desired temperature of heat can be obtained.

The detail construction entering into my invention will be hereinafter more fully described and then speciiically pointed out in the appended claims, and

referring to the drawing forming part of this specification like numerals of reference designate corresponding parts throughout the several views, in which:-

Figure l is a front elevation partly in section of my improved dough raising device, Fig. 2 is a cross sectional view taken on the line .t-x of Fig. l, Fig. 3 is a horizontal sectional view of a portion of the device, taken on the line ywy of Fig. l.

To put my invention into practice, I provide a suitable cabinet l having a lower compartment 2 and horizontally perforated or slotted shelves 3 for supporting pans of bread dough 4. The shelves 3 are detachably supported upon brackets 5 carried by the end walls 6 and 7 of the cabinet.

In order that the condition of the bread dough within the cabinet can be observed at any desired time, I provide the end wall 6 with an opening S covered with a suitable transparent material. The end wall 6 is also provided with a thermometer 9, whereby the temperature within the cabinet or casing can be easily determined.

The cabinet l is provided with front hinged doors l0, to permit of the pans of bread dough being placed within the cabinet, and the rear wall Il of said cabinet is provided near its upper edge with Ventilating openings l2.

In the lower compartment 2 of the cabinet are mounted guide ways I4 for a hot water receptacle l5 which is attached to the removable end plate 16 of the cabinet by bolts I7 and winged nuts 18. The hot water receptacle l5 connects by two-part pipes 1S with a tank l9 said tank having a central llue 20 whereby it can be placed over a lamp 2la or a burner. The tank 19 is provided with an opening 2l whereby the same can be filled with water, said opening being normally closed by a threaded plug 22. The water contained within the tank 1.9 is adapted to co-iningle with the water contained in the receptacle l5, and as the water within the tank 19 is heated by the lamp, the water contained within the receptacle l5 is eventually heated sufficiently to maintain the interior of the cabinet in a warm state, such as is necessary to cause a chemical action of the yeast contained within the bread dough and raise the same.

From the novel construction of my improved dough raising device or cabinet, it will be observed that the parts thereof can be readily removed and thoroughly cleansed, thus insuring a perfect sanitary bread raising device. To remove the het water receptacle, it is only necessary to disconnect the parts ot the pipes 18, remove the tank I9 and the lamp 2l, an d withdraw the end plate 1G and said receptacle.

It is obvious that various changes in the size, proportion and minor details of construction of the cabinet can be resorted to without departing from the scope of the appended claims.

What I claim and desire to secure by Letters Patent, is

1. In a dough raiser, a cabinet provided with a removable end wall, shelves within said cabinet, and guides on the bottom of the cabinet, n waterpan connected to said removable end wall and restingl on said guides for removal from the cabinet with the removal of the end wall, a water-container outside the cabinet, means for heating water in said water-container, and pipes extending through the removd able end wall and establishing' communication between said water-container and said water-pan.

2. In a dough raiser. a cabinet provided with a removable end wall, and havingl a betteln provided with guides, a water-pan received in said guides. bolts connecting said end wall rigidly with said water-pan, a water-container located outside of the cabinet, and pipes extending through the removable end wall and establishing communication between the water-pan :1nd said water-container.

In testimony whereof I atlix my signature in the prosence of two witnesses.

MINTA M. GILL.
